progtest

func ElvishInGlobal ¶ added in v0.21.0

func ElvishInGlobal(p prog.Program) func(ev *eval.Evaler)

ElvishInGlobal returns a setup function suitable for the evaltest framework, which creates a function called "elvish" in the global scope that invokes the given program.

func ProgramAsGoFn ¶ added in v0.21.0

func ProgramAsGoFn(p prog.Program) any

ProgramAsGoFn converts a prog.Program to a Go-implemented Elvish function.

Stdin of the program is connected to the stdin of the function.

Stdout of the program is usually written unchanged to the stdout of the function, except when:

• If the output has no trailing newline, " (no EOL)\n" is appended.
• If &check-stdout-contains is supplied, stdout is suppressed. Instead, a tag "[stdout contains foo]" is shown, followed by "true" or "false".

Stderr of the program is written to the stderr of the function with a [stderr] prefix, with similar treatment for missing trailing EOL and &check-stderr-contains.

If the program exits with a non-zero return value, a line "[exit] $i" is written to stderr.
